When I purchased the vechicle, I was told the everything was 100% in good working condition. The vechicle only had 32,000 miles on it. 2 days after I purchased the Mariner, I tried the front defrost switch and there was no heat whatsoever. I called the dealer and they said that they didn't know if the heater problem was covered in the warranty. I checked the heater hoses at the fire wall and both were hot, this lead me to believe that this vechicle had front end damaged and the heater control for the AC/heater vent door was not reconnected. At this time according to the dealer that the A/C section of the box was warrantied but the heater section is not. Does anyone have any knowedge or ideas to help me with this delemlia.......... contact me at . thank you..........
